关 键 词：the limit equilibrium theory of rock mass the mechanism of water-inrush of seam floor ultimate water-inrush pressure prediction of water-inrush 

摘      要：Based on the limit equilibrium theory of rock mass,we analyzed the mechanism of water-inrush of seam floor and deduced the theoretical formulas of ultimate hydraulic pressure of seam floor through obtaining the facing length,the thickness and lithological association of floor rockmass into ***-inrush risks were predicted according to the geology condition.
